Tag Archives | Austenitisation of Steels

The first step in the true heat treatment cycle of steel is the austenitisation, i.e. to get a homogeneous austenite by heating it to a predetermined temperature in the austenite stability range. Normally, the initial structure of carbon steels, before this heat treatment, is ferrite + pearlite (in hypo-eutectoid steels), pearlite (eutectoid steel), or cementite + pearlite (hyper eutectoid steels).
